Australia’s 2026 Federal Budget: What Proposed Property Tax Changes Could Mean for Investors

As we approach the 2026 Federal Budget, property investors, business owners and family groups will be watching closely for potential tax reform.

According to recent reporting, the Albanese government is considering significant changes to the way capital gains tax is applied to investment assets, including property, shares and other assets. While the final details are yet to be confirmed, the proposals being discussed could represent one of the more meaningful changes to Australia’s investment tax settings in years. At the centre of the discussion is the possible removal of the current 50% capital gains tax discount for assets held longer than 12 months. In its place, the government may return to an inflation indexation model, similar to the pre-1999 system, where investors are taxed on real gains after adjusting for inflation.

For property investors, this is especially important.

A hybrid approach for existing investors

One of the key issues with any major tax change is how to treat existing investments. The reported Treasury proposal appears to avoid a full grandfathering of existing assets. Instead, it would use a hybrid transition system based on how long an asset is held under the current rules versus the new rules.

For example, if an investor held a property for 15 years, with 10 years under the current CGT discount system and five years under a new inflation indexation system, the capital gain could be apportioned between the two regimes.

In simple terms, a portion of the gain would be taxed under the existing 50% CGT discount rules, and the remaining portion would be taxed under the new inflation-indexed model. This approach is designed to avoid the need for millions of investors to obtain property valuations at the start date of the new regime. That would likely be costly, time-consuming and difficult for the Australian Taxation Office to administer. It could also create opportunities for inflated or inconsistent valuations. From an administrative perspective, a time-based apportionment model may be simpler. From an investor perspective, however, the impact will depend heavily on when the asset was purchased, how much it has grown in value, and how long it is held after the new rules begin.

Negative gearing and trusts are also in focus

There is also speculation that the government is considering potential changes to negative gearing, echoing parts of Labor’s 2019 tax agenda. In addition, Treasury has reportedly examined changes to the taxation of trust distributions, including a possible minimum tax rate of around 25% to 30%. This would be significant for family groups, small businesses, farmers and high-net-worth individuals who commonly use trust structures. The broader theme appears to be a push toward a tax system that treats different forms of income more evenly and fairly, while also raising revenue and addressing intergenerational equity.

Why this matters

For many Australians, property is not just an investment asset. It is a major part of long-term wealth planning, retirement strategy and family financial security. Any changes to CGT, negative gearing or trust taxation could influence:

• Property investment decisions
• Holding periods for existing assets
• Cash flow and after-tax returns
• Estate and succession planning
• The use of family trusts and business structures
• nvestor confidence in residential property

The important point is that these proposals are not simply technical tax changes. They may affect real decisions made by landlords, investors, business owners and families across Australia.

Planning ahead

At this stage, investors should avoid making rushed decisions based on speculation. However, it is sensible to be prepared. Property owners and investors should be reviewing their portfolios, understanding unrealised capital gains, checking ownership structures, and considering how potential changes could affect long-term plans. The 2026 Federal Budget may provide more clarity on whether these reforms will proceed, when they may commence, and how transitional arrangements will apply. For now, the key message is this: tax policy is moving back into the centre of the property investment conversation. Investors who understand the potential changes early will be better placed to make informed decisions once the budget details are confirmed.
